Guys, my hat is off to you, the more I play with this little gem, the more I love it! This is just so much fun :)
It appears that you can define multiple layers as Still and if you use masking here it can create very interest possibilities. If you enhanced the blend modes and masking I'm going be spending most of my time shooting short video segments and playing
with this, so please stop development right now :)
All the best,
Robert
